Functions
Skin Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
Locks in moisture
Traditional Use
Discovered as a single-celled green algae in the early 20th century and studied for nutritional content. Modern use in skincare emerged in the 1960s when Japanese researchers identified its antioxidant and skin-conditioning properties.
